FEEDING MECHANISM FOR COTTON-GINS.

Original application filed March 1, 1910, Serial No. 546,729.

Serial No. 613,343.

To all whom it may concern:

Be it known that I, Anonrn RIEMEN- soimnionn, a citizen of the UnitedStates. residing at Sarco Creek, in the county ()Tli Goliad and State ofTexas, have invented certain new and useful lmprowments in FeedingMechanisn'l for Cotton-(fins, being a. division of my application forpatent for gin plants, Serial No. 516,729, filed March 1, 1910.

Th5 present invention relates to cotton ginning plants and consistsrimarily of peculiar mechanism controlling the feeding of the cottonsupplied to the gins.

The novel features of the invention will be presented more clearlyhereinafter, and for a full understanding of the same, referonce is tobe had to the accompanying drawings. in which Figure 1 a side elevationof certain parts of a ginning plant, illustrating more particularly thegins, supply pipe leading thereto and the feed controlling mechanisn'lassociated therewith; Fig. 2 is a sectional view taken about on the line2-2 of Fig. 1, and bringing out more clearly the parts ot the feedmechanism.

'lhroughout the following detail description and on the several figuresot the drawings, similar parts are referred to by like rett'erencecharacters.

Referring particularly to the drawings 1 denotes the usual supply pipeemployed in a cotton ginning plant, 1nd leading from a point exterior tothe ginning room to the several gins 2. The gins 2 may be of anyconventional type and a seed conveyor 3 leads from their lower ends aswell as a lint delivery pipe 4, the latter extending to a suitablecondenser, not shown. The outer end of the supply pipe 1 is providedwith a downwardly turned portion 1 carrying a telescopic section 5adapted to be lowered into a wagon, from which the cotton is taken inits crude state and delivered to the ginning plant.

The end of the supply pipe 1 opposite the portion 1' leads to av blower(3 from which extends the ventilator 7, said blower being of anyconventional type and creating a suction in the pipe 1 sutliciently todraw the cotton from the Wagons to deliver the same in proper quantitiesto the gins 2. A partition 8 of toralninous material is located in thelength of the supply pipe 1 and situated Specification of LettersPatent.

Patented Sept. 23, 1 913.

Divided and this application filed March 9,

just beyond the point where said supply pipe has its delivery opening 1leading to the gin 2 more remote from the outer end 1 ct said supplypipe. During the operation of the ginning plant, the blower (3 creates asuction in the pipe 1', drawing the cotton to the gins 2, and thefeeding mechanism comprising this invention is designed tointermittently cut oil' the suction of air in the pipe 1, with respectto the blower (3, generating said suction. The 'leeding mechanismconsists preferably of a valve 9 located between the blower (3 and theforaininous partition 8, and pivoted at its upper end, as shown at 10.The valve 9 engages a fixed annular valve seat 9, as shown. The freelower end portion oi. the valve 9 is connected by an operating rod 11.with a lever 12 pivoted between its ends to a bracket 13 adjacent to thesupply pipe 1. The rod 11. is connected with the upper end of the lever12 and the lower end of said lever operates in contact with a cam '14-carried by the outer side of a gear 15, the latter being supported by anaxis 10. The gear 15 is in mesh with a spur-gear 17 driven by a bevelgear 18 which meshes with a bevel gear '15) on the drive shaiit 20, saiddrive shaft being driven by a pulley 2i and bel t 522, the latterconnected with a suitable source of power.

Under normal conditions a spring 23 connected at one end to the bracket13 and at the other end to the upper end oi the lever 19, tends to holdsaid lever in engagement with the cam 1 Cam 14:, as apparent from Fig.1, is constructed with approximately one-half of its circuin'tcrencehaving a greater radius than the other half the meeting halves beingconnected by abrupt shoulders whereby rotation of the cam in onedirection is rendered impossible because of the resultant engagement ofone of the shoulders with the lower end of lever 19,, but the cam isfree to rotate clockwise, that is from left to right above the axis, thelower end of the lever 12 dropping off of one shoulder as it passes fromthe enlarged portion oi the cam, that is, passcsttrom. the portionhaving the greater radius to the reduced portion, or portion having lessradius. the opposite shoulder during the continued rotation of the camstriking the lever l2 above its lower end, the lever being disposed atan incline to the vertical, and the shoulder thus swinging the leverlaterally on its pivot and i1nparting a longitudinal forward thrust tothe link 11 whereby the valve 9 is positively and continually closedagainst the pressure of the spring 23, supplemented by the atmosphericpressure rendered active by the exhaust from fan 6. The valve 9 willremain closed so long as lever 12 is engaged by the enlarged portion ofcam 14-, and during the continued rotation of the cam, when the enlargedportion passes the lower end of the'lever, and allows the lower end ofthe lever to swing toward the axis of the cam, the upper end will bepermitted to swing in an opposing direction, and under the stress of thespring 23, will move link 11 in a direction for opening valve 9, thevalve being opened by the pull of the spring, supplemented by theatmospheric pressure acting against the face of the valve. e 7

Having thus described the invention, what is claimed as new is: V

1. In a device of the class described, the combination, with a suctionpipe having an intake and an exhaust, a gin receiver communicatingtherewith intermediate its ends, means for exhausting air from the pipethrough the exhaust end, a valve adapted to be closed against theexhaust, said valve being disposed within the pipe between the ginreceiver and the exhaust means, a pivotally mounted lever having one endconnect-- ed with the valve for actuating the same, a cam engaging thelever and shaped to move the lever upon its pivot in a direction forclosing the valve, and means for rotating the cam for effecting theclosing movement, the cam being formed with the reduced portionpermitting movement of the lever to a position with the valve open;

2. In a device of the class described, the combination, with a suctionpipe having an intake and an exhaust, a gin receiver communicatingtherewith intermediate its ends, means for exhausting air from the pipethrough the exhaust end, a valve adapted to be closed against theexhaust, said valve being disposed within the pipe between the ginreceiver and the exhaustmeans, a pivotally mounted lever having one endconnected with the valve for actuating the same, a cam engaging thelever and shaped to move the lever upon its pivot in a direction forclosing the valve, means for rotating the cam for effecting the closingmovement, the cam being formed with the reduced portion permittingmovement of the lever to a. position with the valve open, and a springcon nected with the lever for subjecting the same to spring pressure ina direction tending to open the valve.

3. In a device of the class described, the combination, with a suctionpipe having intake and exhaust ends, a gin receiver communicating withthe pipe intermediate the ends, a valve within the pipe hinged to swingto and from a closed position and disposed between the gin receiverand'exhaustend of the pipe, a tan communicating with the exhaust end ofthe pipe for exhausting air from the pipe, a rotatably mounted cam havinan enlargementand a reduced portion'with shoulders connecting theenlargement with the reduced portion, means for ro tating the cam, apivotally mounted lever having a free end resting against the cam andadapted to be swung by the engagement of the enlargement with a portionof the lever, the lever being free to swing in the opposite directionwhen disconnected from the enlargement of the cam, a link pivotallyconnected to the lever at the opposite side of the pivot of the leverfrom that of the free end, said link being piv'otally connected to thevalve at that side ofthe valve adapted to close the valve during themovement of the lever'under actuation by engagement with the enlargedport-ion of the cam with the lever;

In testimony whereof I aflix my signature in presence of two Witnesses.
